Journal of Applied Ecology publishes novel papers that apply ecological
concepts, theories, models and methods to the management of biological resources
in their widest sense. The editors encourage contributions that use applied
ecological problems to test and develop basic ecological theory, although there
must be clear potential for improving management. The journal includes all major
themes in applied ecology: conservation biology, global change, environmental
pollution, wildlife and habitat management, land use and management, aquatic
resources, restoration ecology, and the management of pests, weeds and disease.
Articles that interact with related fields are welcomed providing that their
relevance to applied ecology is clear. Further details are available at www.journalofappliedecology.org.

The "moving wall" represents the time period between the last issue
available in JSTOR and the most recently published issue of a journal.
Moving walls are generally represented in years. In rare instances, a
publisher has elected to have a "zero" moving wall, so their current
issues are available in JSTOR shortly after publication.
Note: In calculating the moving wall, the current year is not counted.
For example, if the current year is 2008 and a journal has a 5 year
moving wall, articles from the year 2002 are available.

Terms Related to the Moving Wall

Fixed walls: Journals with no new volumes being added to the archive.

Absorbed: Journals that are combined with another title.

Complete: Journals that are no longer published or that have been
combined with another title.

Abstract

(1) A study was made of the effect of secondarily treated effluent on the phosphorus budget of a central Florida freshwater marsh. The marsh was chiefly composed of Sagittaria lancifolia. Pontederia cordata. Panicum spp. and Hibiscus sp. Three 2000 m$^2$ plots received effluent at the rates of 1 3. 3.8 and 10.2 cm wk$^{-1}$, while a fourth 2000 m$^2$ plot was a control plot which received 3.8 cm wk$^{-1}$ of freshwater. (2) In the first year the plot receiving the high rate of effluent showed increased net production of plant shoots, increased litter production, increased root and rhizome production and higher phosphorus concentrations in living and dead plant tissue compared with the control plot. (3) Effluent treatments did not significantly increase the phosphorus concentrations measured in the groundwater draining from the experimental plots. All the wells within the effluent plots had phosphorus concentrations c. 97% less than the phosphorus concentration of the applied effluent. (4) Phosphorus budgets were constructed for the control plot and the plot receiving the high effluent treatment. Over the course of the study 38.03 g P m$^{-2}$ were applied to the high effluent plot. Of the total input 26.31, 8.81 and 1.97 g P m$^{-2}$ were stored in the soil, roots and rhizomes, and litter respectively. Outflow of phosphorus from the plot amounted to only 0.94 g P m$^{-2}$ The freshwater control plot received a total of 0.38 g P m$^{-2}$ Storage in the litter accounted for 0.21 g P m$^{-2}$ and outflow accounted for the remaining 0.17 g P m$^{-2}$ There was no evidence of a spring flush of phosphorus from either the control or effluent plot. (5) The marsh successfully removed phosphorus from the effluent during the first year of application. It was concluded that long-term use of the marsh for phosphorus removal may be contingent upon the phosphorus adsorption capacity of the soil and the rate of peat production.
